Right, and backed by the source.
Accuracy asks whether the answer is correct. Groundedness asks whether it came from the sources you gave it. You want both.
Accuracy
Is It Correct?
- Check answers against a trusted source
- Use questions where you know the answer
- Score right, partly right, or wrong
- Track it by topic, not just overall
Groundedness
Is It From The Source?
- Every claim traceable to a document
- No facts added from outside
- Citations that point to the right passage
- “I don't know” when the source is silent
Correct and traceable.
